Editorial policy

Price retrieval, calculations and list rendering are automated. Symbol pages are generated from price data and are excluded from search and advertising.

How text is made

AI drafts the site's articles, glossary entries and explanatory pages.

When figures in an article are recalculated separately, the article shows the method and result. A figure is not described as independently recalculated unless that check was performed.

What the operator decides

The operator chooses the listed markets, Japanese names, wording rules, pages eligible for advertising, and corrections. The operator page records those decisions with dates.

Numbers and wording

Numeric labels match their calculations. A figure is omitted when the required data is unavailable; figures are not invented, interpolated or approximated. The site does not publish price forecasts, investment advice or venue promotions.

See the correction policy and log for error handling and the operator page for the operator's role.

Data sources and coverage

Price lists use Hyperliquid perpetual-futures data. Contracts carry names for stocks, indices, commodities, foreign exchange and crypto; these are distinct from cash-market trades and official index feeds. Displayed prices reach the browser through this site’s API.

Earnings and dividend records use SEC EDGAR filings. The periods and units belong to the relevant company filings. Periods without a filing and values whose mapping cannot be confirmed are excluded. Fourth-quarter figures are not filled in by subtracting from annual totals.

Published CPI, payroll and unemployment figures come from the U.S. Bureau of Labor Statistics (BLS). Price series, company disclosures and economic statistics are separate datasets, not a single observation with a shared update time. About the data describes the retrieval paths and coverage.

Times and comparison bases

An article’s coverage period is the period used in its calculation. The text’s update date and the retrieval time of a price or statistic are separate fields. Explanations using saved values refer to those saved observations. The date of the text is not the retrieval time of a current price.

An explanation of a percentage change carries the basis used for that figure. A provider-reference comparison is distinct from a comparison at the cash-market close. A calculation using perpetual-futures reference prices is not described as a change in cash prices themselves.

Reporting and recording corrections

The contact page accepts reports about text, figures, source links and comparison bases. The page URL, passage, observation time and supporting source identify what is being reported. For display problems, the device and viewport width also help identify the affected area.

Correction records separate the surface and period, previous and correct displays, and correction time. SHA-256 identifies the supporting saved record. Receiving a report and publishing an evidenced correction are separate stages; an incoming report is not itself a completed correction record.
